Abstract: FIELD: optics. 
     SUBSTANCE: invention relates to fibre-optic equipment and is intended for use in creation of remote electric power sources based on light guides, laser medical apparatuses and other unit, and apparatuses utilising systems for transmitting laser emission through a light guide. Claimed is a method for introducing powerful multimode pulse laser emission into a light guide, wherein a laser, a lens and a light guide secured in an adjusting apparatus wherein a converging laser emission beam is formed using a lens, are used, installed sequentially on the same optical axis and optically connected. The light guide is located in the focus of the lens, and when the adjustment apparatus is used, the end of the light guide is placed in the area of the focal spot of laser emission created by the lens. By glass dividing plates installed along the course of propagation of the laser beam and by a mirror installed after all of the glass plates, the laser emission is divided into equal parts, each of the parts is focused by the lenses and introduced into intermediate light guides through focons, and all intermediate light guides further combined into one used to transmit the laser emission. The ends of the focons are therein placed in the area of the focal spots of laser emission, created by the lenses using the adjusting apparatuses for securing focons.

Abstract: FIELD: rare earth metals.  
     SUBSTANCE: invention relates to the technology of processing ores and concentrates containing rare earth elements (REE), and can be used to obtain REE from low-concentrated or secondary raw materials at the stage of separation of the sum of lanthanides using the ion flotation method. La (III) is extracted from an aqueous solution of lanthanum (III) nitrate obtained by processing monazite. Monazite is leached to form an aqueous solution of REE, which is sulfatized to obtain double sulfates and filtered to form a solid and aqueous phase. Alkali is added to the aqueous phase and hydroxides are precipitated. The aqueous and solid phases are obtained. The solid phase is dissolved in HNO 3  to obtain the aforementioned aqueous solution of lanthanum (III) nitrate, to which an anionic surfactant, sodium dodecyl sulfate, is added as a collector in the molar ratio La(NO 3 ) 3 :C 12 H 25 OSO 3 NA = 1:3 in a concentration corresponding to the stoichiometry of the reaction for ion flotation, and sodium chloride to a concentration of 0.01 mol/l chloride ions. The resulting mixture is stirred for at least 15 minutes and the pH of the solution is adjusted from 7.8 to 8.6, undergoes thermostatic control at a temperature of 20 to 25°C. The resulting foam is destroyed with 2N sulfuric acid to obtain a foam product. The foam and water phases are analyzed for the content of lanthanum (III) cations and the distribution coefficient of lanthanum (III) cations between the aqueous and foam phases is calculated. The foam product is sent to the drying cabinet for thermal decomposition to produce lanthanum oxide.  
     EFFECT: method contributes to an increase in the distribution coefficients of lanthanum cations between the foam and aqueous phases, and consequently, the efficiency of extraction of lanthanum cations from solutions of their salts.

Abstract: The guide control on a shoe-welting machine is designed to prevent excessive pressure from being applied between a sole edge and pressure plate. Any such excess pressure, built-up when welting tongs are set in their operating position, is indicated by a pressure indicator whose signal triggers a pressure drop. The signal causes the pressure plate to drop under control of a valve which opens another valve, tripping a counterpressure. The tripping valve acts on a piston. A wedge for the sole edge, once removed, acts upon a third valve blocking the counterpressure. PS.
